whose post-oiline address is 1507 Fifth avehue, Coroapolis, Pennsylvania, alt'oresaid,

have made certain new and useful Improve ments in Car-Brakes, of which the following is a specification' Th's invention relates to brakes for railway cars and more particularly to hand operated brakes adapted to be secured to the ends of freight cars, although it may be used for other purposes, and the object of the invention is to construct a brake which will have very few parts, constructed with very little machine work, readily assembled into position and one in which the parts will 29 hang by gravity in the position where they will occupy the least amount of room.

The invention consists in a brake of this 1 character, such as shown, in its preferable embodiment, in the accompanying drawings,

. and as will be hereinafter described and claimed.

In the aforesaid drawings: Figure 1 is an end view of a car having my invention applied thereto. Fig. 2 is a vertical central 3 section illustrating my invention on a much larger scale. Fig. 3 is a per's ective view showing the various parts detac ed and, separated in order to better show the construction. Fig. 4 is a detail-sectional view of 35 the gravity pawl for holding the ratchet.

Referring now to the details of the drawings by numerals: 1 designates a frame, preferably a malleable casting, which is adapted to be secured to the end or any part .of a car, by riveting, in some such position asthat shown in Fig. 1. This frame 1 is illustrated in sectional View in Fig. 2 and is shown detached in perspective View in Fig. 3 and as shown in these two figures, it

. I will be seen that it comprises a hollow hous ing and an annular ring t projecting from the housing 3. The frame 1 is provided with apertures 6 and 8 concentric with the annular ring 4 for the purpose of forming bearings'for an axle 10 which forms a windlass for the brake chain 12, the axle 10 being secured within the frame 1 by means of a cotter 14; as illustrated in Fig. 2. The axle 1.0 is provided with a headed end 16 which projects at some distance beyond the ring 4 of the frame 1. Between the headed end 16 of the axle 10 and the ring 1 of the main frame 1 is supported a movable member 20 which has an annular part 22 which is substantially the same shape as the ring 4 and when in position forms a continuation of said ring, the annular ring and the annular part 22 forming'a pocket within which is housed a ratchet wheel 30 as illustrated in Figs. 2 and 3. This ratchet wheel 30 is keyed to the axle 10 by means of the pin 32 and the parts referred to are assembled as follows: The axle 12 is inserted through the opening in the member 20, then the ratchet wheel 30 is slipped over the ratchet wheel and the axle 10 so as to hold the two in fixed relation to each other. Then the member 20 with the axle 10 and ratchet wheel are placed in position with respect to the main frame 1, by inserting the axle 10 through the openings 6 and 8 until the annular member 22 joins the annular ring 4. and is coincident therewith, as illustrated in Fig. 2; and when the parts are in the position just described, the cotter 14 is driven through the axle 10, when the parts will be properly assembled.

The ratchet wheel 30 serves the double function of the two ratchet Wheels commonly. employed in this character of brake and .it therefore cooperates with the parts now to be described. The annular ring 4' has formed on it a bearing 34 to which is pivoted a gravity pawl 36 by means of a countersunk piv0t38, the inner end of the pawl 36 projecting. within an opening t the bottom of the annular ring 4 so as to lie in the path of the teeth of the ratchet wheel 30 as illustrated in Fig. 4. From an inspection of Figs. 3 and d, it will be seen that the longer end of the ratchet 36 will form a weight to normally hold the inner end 36 in contact with the teeth 30. In order to take part of the strain off of the pivot 38, I form the pawl with 2. lug 40 which, when the awl is located between ,any two of the rate et teeth, strikes against a wall 42 of the bearing 3st and thus relieves the pivot 38 of partof the strain. The member 20 hereinbefore referred to forms a socket to receive a handle .or lever 50 which is held within the socket 20 by means of a bolt 52, as illustrated in Fig. 2. This bolt passes through a slot 5&1: in the inclo'sed end of the the axle 10 and the pin 32 driven through lever or handle and .the construction is respect thereto, an axle passing through said such that when the 'handle .is pushed :Withrecessed members, a ratchet wheel secured in the socket in the position shown in full to said axle and located between said relines in Fig. 2, the end of the lever 50 which cessed members and a lever cooperating with 5 is formed with teeth engages the teeth the movable member, and with said ratchet of the ratchet Wheel 30 so that'when the lewheel adapted to rotate said movable mem' ver 50 is swung in one direction-the ratchet ber and the axle and ratchet wheel with rewheel 30 and.the axle 10 will be caused to spect to the frame and said first recessed rotate, thus winding the chain 12-on the inmember 10 closed part of the axle-l0, the gravity pawl 3.
